An archived webinar posted on the Web site of our sister publication
Medical Design introduces a technique for making complex component
geometries using a specialized process of chemical etching and diffusion
bonding. Topics covered include the basic concept of how photo chemical
etching works, what materials can be etched, limitations involved in
photo etching, how etched product is diffusion bonded, limitations
involved in bonding etched product, and where and how this technology
can be applied.

Microbial counts on computer keyboards can be more than 60 times
higher than on toilet seats, averaging 3,300 bacteria/in.2
Public surfaces, such as those of ATM machines, present even greater
possibilities for the product damaging microorganisms.The good news is
that a new HM 4100 antimicrobial additive from Biosafe Inc., Pittsburgh,
has a structure engineered to puncture and rupture cell walls, killing
99.99% of the microbes on plastic surfaces in about 4 hr.

FREE FRICTION CD FROM GENERAL
MAGNAPLATE
 Reduce
production downtime and minimize replacement costs by solving wear,
corrosion, and release problems on metal parts with a FREE CD-ROM from
General Magnaplate. The easy-to-use CD assists design engineers in
selecting
permanent coatings that prevent wear, friction, corrosion, sticking,
galling, and chemical attack on ferrous and nonferrous metals. The CD is
useful for comparing the static and kinetic coefficient of friction
(COF) of
numerous metals with 20 Magnaplate-applied 'synergistic'
coatings.

In response to market demand, a tape manufacturer modified its most
popular electrical tape to make it fire retardant. The first salesperson
to demonstrate the tape pulled a length of it from the roll and applied
a lit match to the bottom end. The hanging length of tape burst into
flame, causing minor damage to the carpeting and burning holes in the
salesperson’s suit.

A thermoplastic elastomer (TPE) is the outer skin of a sensor strip
that will help protect pedestrians if they step into the path of a
moving car. The sensor is currently installed in the “active
bonnet” of Jaguar XK and Citron C6 models.

The Elastocon SMR Series of thermoplastic olefins (TPOs) have good
flow properties for filling large complex parts. They can be injection
molded, extruded, thermoformed, and blow molded. They are candidates for
automotive body panels and bumper facias thanks to cold weather impact
resistance down to −30°F. They mold with a high gloss finish
that resists scratches during handling and delivery. The TPOs are UV
stable and come in a range of Shore D hardnesses. They are compatible
with standard in-mold decorating, pad printing, hot foils and stamping,
and various proprietary decorating processes. The TPO Series comes in
black or natural (for coloring or colored) and are RoHS and California
Proposition 65 compliant. Natural grades also meet FDA requirements.

A new flexible, tough epoxy potting and encapsulation compound
called EP30FL can be used in both thick and thin cross sections. It is
100% reactive and contains no volatiles. The compound generates low
exotherm during cure though it cures relatively quickly at room
temperature. It shrinks little during curing and bonds similar and
dissimilar substrates. Its flexibility makes it a candidate for use in
environments exposed to thermal cycling. Additionally it withstands
mechanical shock and vibration, is water resistant, and in the cured
state can serve as an electrical insulator. The compound comes in half
pint, pint, quart, gallon, and five gallon kits.

Two-component polyurethane coatings contain little or no solvent
other than water so they emit few volatile organic compounds (VOCs) into
the environment. The problem is, it takes them a long time to cure on
plastic or on wooden surfaces. Neither can be heated to high
temperatures without suffering damage. Binders from Bayhydrol UV aqueous
polyurethane dispersions, however, make possible coatings that are both
environmentally friendly and cure quickly under UV light. Depending on
the equipment, the curing process — which covers drying and UV
crosslinking — can be shortened to less than five minutes.
Coatings made with the solvent-free Bayhydrol UV XP 2649 are just as
insensitive to water and solvents as conventional two-component
polyurethane coatings and can be used to give plastics a soft,
expensive-looking finish.

Rev up your interdisciplinary design skills
What happens when a microcontroller turns on a power FET, sending a
current pulse to a motor coil that develops a magnetic field which turns
the rotor shaft, advancing a timing belt that drives a pair of nip rolls
suspended on bearings in a web-processing operation on a form, fill, and
seal machine installed on a potato chip line at a Frito Lay plant in
central California? And how can you be sure that the encoders, prox
sensors, and other feedback devices you plan to use will accurately see
and report every relevant motion, machine state, and process condition?
And will the signals get through the networks fast enough, without being
corrupted, giving the controllers time to execute their algorithms as
intended? It's a lot to think about, and it only scratches the surface
of what many engineers grapple with today. If you happen to be one of
them, then the place for you — where you can find answers and meet
others with similar concerns — is www.Mechatronic-Design.com.

Two-Shot Silicon and Thermoplastic Molding:
The Innovative Cost Saving Solution for Medical OEM's
Sponsored by Saint-Gobain
DATE: April 2nd, 2008
TIME: 2:00pm ET/11am PT
Medical device designers are facing intense pressure to create
innovative designs and maintain the highest quality over a product's
lifecycle while also being forced to design for lower cost
manufacturing. This is a challenge we recognize, but one that can be
overcome by leveraging the cost savings and benefits of two-shot molding
technology. Saint-Gobain's engineering team will present on two-shot
molding, how this process innovation can provide cost savings, increased
design freedom, and provide the quality and performance you demand.

Gearmotors: Achieving the Perfect Match
Success through optimized motor & gearbox integration
Sponsored by Groschopp
DATE: April 9th, 2008
TIME: 2:00pm ET/11am PT
How do you select a motor and a gearbox (speed reducer) separately, then
perfectly match them for your OEM application? Is it better to specify
a pre-engineered gearmotor? Does it make a difference?
These are the questions that will be answered in Groschopp's upcoming
webcast. Groschopp engineers Matt Decker and Loren Kamstra will share
tips, tricks and techniques for specifying the most efficient and
cost-effective choices given a variety of application considerations.
Review of actual Case Studies will bring their experiences to life and
reinforce your new motor/gearbox/gearmotor knowledge.

Wireless Sensor Networks
A Surveer of Design Options
Sponsored by Winland Electronics Inc.
DATE: April 30th, 2008
TIME: 2:00pm ET/11am PT
Developing a wireless sensor network can be an awesome challenge or a
simple matter of picking the right module, depending on who you ask.
Off-the-shelf solutions have certain advantages, but may not be the best
overall solution to your problem. Home grown or custom solutions can be
designed to overcome specific challenges, so they can be critical for
certain projects. Learn more about the technical pros & cons of both
options in this live course.

More custom-rubber-molding
knowhow
|
Holz Rubber
Co. has expanded its custom rubber molding capabilities with the
addition of phenolic resin molding. Phenolics are the result of
polymerization between resin and a base material that can be paper,
glass or even Kevlar. The base material used depends on the intended
application of the finished product. Phenolic resins are strong and
durable which makes them suited for industrial application including oil
drilling equipment, petrochemical products, mechanical seals, and
consumable rubber parts. Holz Rubber can make OEM replacement parts as
well as propitiatory components. It specializes in parts weighing
between a couple grams and 400 lb with runs between a few hundred and
several thousand.
